Yathmags

Yathmags are giant floating aberration heads, and a Yorbie rides one of them in the back of the fight S3E1·01:26:40. Ally asks whether he said "yas queen," and Brennan insists the word is Yathmags S3E1·01:26:53 S3E1·01:26:55. Brennan says the yathmags are more like the ants than like the Yorbies, and a disintegration effect comes toward the party that is magical but not a spell S3E1·01:29:21 S3E1·01:29:31 S3E1·01:29:35.

Yathmags are giant floating aberration heads ridden into battle by Yorbies, in the same way other Yorbies ride giant ants S3E1·01:26:40 S3E1·01:29:21. One produces a magical disintegration effect aimed at the Bad Kids that is not a spell S3E1·01:29:31 S3E1·01:29:35. In the second part of the fight Brennan says the Yathmags cannot do their mouth thing and the ants cannot do their attacks S3E2·00:33:02. He pronounces the name "Yas-mag" S3E2·01:04:25.
